to house said hook in a protective manner, a lever being employed inconnection with a pin and passages in a gearing forthe swingable` hookfor retaining the hook in xed position when folded" or extended, manualmeans anda spring. con.- trolling the release and automaticswingingmovement of the hook to an operative position.

The invention willY be best understood from a consideration of thefollowing, detailed4 description, in View of the accompanying4 drawingsforming part of the specification', nevertheless, it is to be understoodthat the invention is not confined to the disclosure, being susceptibleof such changes and modifications which shall define no materialdeparture from the salient features of the invention as expressed in theappended claim.

In the drawings:

Figure 1 is a fragmentary vertical longitudinal section of my foldablegaff hook shown extended into an operative position,

Figure 2 is a fragmentary vertical longitudinal section of the hooktaken at right angles to the section shown in Figure l,

Figure 3 is a fragmentary longitudinal vertical section similar to thatshown in Figure l but disclosing the hook folded,

Figure 4 is a transverse horizontal section along the line 4 4 of Figurel,

Figure 5 is an enlarged fragmentary vertical section of the lower end ofthe handle showing the hook rested therein.

Figure 6 is a side view of the foldable hook extended to an operativeposition from the handle, and

Figure 7 is a side view of the handle showing the gaff hook foldedtherein.

Referring more particularly to the drawings, l il designates a handlewhich is formed of a well known plastic and which is substantiallyhollow except for the portion I I at the lower end. Rivets or screws I2,I3 and I4 connect a cover plate Illa to the handle ID and serve otherpurposes which will be explained presently. The rivet i4 is located inthe lower solid portion of the handle for aiding in securing thesections of the handle together. A pocket I5 is formed in the solid endmember.,

of' the handle-.toreceive the hook I6 pergse while the'sharpened, pointl1 engages a pad I8 formed of sponge. rubber.

Itwillbe noted fromFigure l that the handle has a.: rear end wall and a.front end wall 2I which is tapered lengthwise. The walls provide anarrow longitudinal chamber 22 Within the handle. Y

A channel member 23 is located in the chamber 22 andv secured in placeby the screws or rivets I2 andv I3 and' has its open end facing theremovable plate` Illa; A coil spring 24 has-the lower end connected to apin 25 carried by thevchannel TheA upper end` is attached to an eye 25on the lowerend; of a wire cable 21.

Ashank oft the hook It4 extendsv through. ani opening at, the upper:end' of a metalk casing- 3|; which is pressedonto the upper'reducedendofY thehandle; I0. This casing: iscutaway' asshown at' 32 inv Figure'3. in the-'front' and.. side portions thereof to permit the shank; tomove from its. operative position (Fig.L 6j) to its inoperative orclosed positiontFig. 7).

The shank is formed integrally with a disk 33 providing a hub ortrunnion which is rotatably mounted on a pin 34 carried by the sideflanges of the channel member 23. The disk is provided withdiametrically disposed perforations 36 and .31 for a purpose which willbe explained presently. The periphery of the disk has a groove 38,concave in cross-section, for receiving the cable. The cable is attachedat 39 to the disk.

A lever 40 is pivoted at 4I on one face of the channel member 23. Thislever is slightly bent so that one end 42 is normally spaced from saidface by a coil spring 43 (Fig. 2). The outer free end of the lever has apin 44 disposed above the cut-away portion 32 of the casing 3| and isadapted to be received by one of the perforations 36 or 3l for retainingthe gaif hook extended from the handle or folded therein. A button 45 issecured to the lower end 42 of the lever 40 and normally seats in adepression 46 in the handle to prevent accidental actuation of thelever. The ends of the spring 43 are secured respectively to the face 41of the channel member and to the portion 42 of the lever 40. Said springis received by a passage in the other face 48 of the channel 23.

" A pin 5l! secured to the disk 33 projects from opposite `faces of thedisk and is adapted to engage a straight portion 5I on the upper end ofeach flange of the U-shaped channel 23 for retaining the ga' hookextended (Figs. l and 2). When the hook has been closed the pin 53 willelements of a boat so that the point will be in y condition for use.

of said shank for holding the latter in said extended or retractedposition, said means comprising a lever arranged in face to face spacedrelation with respect to said disc and plvotally mounted intermediateits ends for rocking movement about an axis transverse of and spacedfrom said disc, a pin projecting transversely from one end of said leverand normally engaging the one of said perforations corresponding to theretracted position of said shank, a coiled spring arranged transverselyof said lever adjacent the other end thereof and having one end securedto the face of said lever facing said disc and hav- When it is desiredto use the hook, the handle is grasped by the hand of the operator withVthe end of the handle having the cap or casingl pointing outwardly fromthe body. The thumb of the operator is pressed on the button 45 whencethe lever 40 will be rocked and raise the pin '44 .Y out of theperforation 31. The spring 24, which tends to rotate the disk 33 willrevolve said disk and thrust the gaf hook to the operative positionshown in Figure 6. The pin 44 will fall automatically in the perforation36 after the rotating disk has brought theperforation in alignment withthe pin.

When the Work has been completed the shank 30 is returned manually tothe position shown in Figure 7, after the button 135 has been depressedto release the pin 44 from the perforation 36 in the disk 33. The spring24 is under tension when the hook is folded into the handle.

What I claim is:

In a gai hook, the combination with spaced flanges, a disc carrying ashank rotatably supfiported between said nanges inwardly of one endthereof, said disc being provided with a pair of circumferentiallyspacedl perforations corresponding to an extended and a retractedposition forsaid shank, and spring means operatively connected to saidshank for normally biasing the latter into said extended position, ofmeans selectively engageable with the spaced perforations ing the otherend secured to a supporting surface `for urging the other end outwardly,hand actuable 'means on the other face of said lever adjacent the otherend thereof for moving the other end of said lever inwardly to therebycause rocking movement of said lever about said axis and disengage saidpin from said one of said perforations, and another pin projecting fromthe opposite faces of said disc and engageable with means on said oneend of said flanges for retaining the shank in the extended position.
